My 2.75" Security Six is a LOT easier to shoot than my SP101s and not a whole lot bigger or heavier.
My GP100 3" and 4" are both a lot bigger than my SP101 but are more accurate and enjoyable to shoot.
I opine that my SP101s will outlast any other similarly sized .357 magnums fed a similar diet of ammunition.
Talking only about double action: I will admit that my .22RF SPs and .357 Magnum SPs have stock springs and would benefit from some trigger work and aftermarket springs. But my Sec Sixes and GPs (and Redhawks and Super Redhawks) all have stock springs and never had any action smoothing, either.
In single action, all are about equal, so gun mass and sight picture rule. SP101 and LCR tied for worst and all the rest equal but for sight radius.
Where do they fall in the spectrum of Rugers in general?
I would say they are as strong as the Sixes, almost as strong as the GPs and a lot stronger than the LCRs. Rating the ease of shootings, though, I would put the LCR at the top, security six and then the GPs and both Redhawsk all very close together and the SPs 'way far behind. Sights, though really hurt the LCRs. The sights hurt the SPs, too, but with the handicap of the lousy trigger on the SP, the sights handicap is not significant.
On a scale of 100,
SP101 30
LCR 30
GP100 65
Sixes 75
Redhawk 95
Super Redhawk 100
But if you rate weight, strength, accuracy in single action, accuracy in double action, concealability, comfort of shooting differently than I, you will come up with different figures and likely, different ranking order.
Heck, I might come up with a different ranking order tomorrow myself. This is so subjective.
